3 Claims. v(0l. 226-66).

The invention relates to a liquid dispensing nozzle and more especially to'a. gasoline filler hose dispensing of gasoline for the iilling of a gasoline tank, particularly those equipped on motor vehicles, a signal will be-had showing that gasoline is being supplied to the said tank and the instant that the tankis lled the signal stops thus signifying the fact that the tanky has become filled and in this Way avoiding the over-l lling ofsuch tank during the dispensing operation of`v the gasoline.

A further object of the invention is the provision of va nozzle of this charaoter, wherein anovel closure member is associated therewith so as to enable the covering of the lling spout of a gasoline tank irrespective of the closeness of said spout to the body of amotor vehicle'having the' tank a part of its equipment and such closure seals the mouth end of the spout so that in cooperation with the nozzle an overflow of the tank will be avoided and at the same time la notice Will be given the instant that the tank becomes filled with gasoline dispensed from-the nozzle.

A still further object of the invention is the provision of a nozzle of this charaotenwhich is simple in its construction, thoroughly reliableand eicient in operation, capable Aof fitting vwith the filling spout .constituting parts of varying types of gasoline tanks and their arrangement in a motor vehicle in that some lling spouts are located in contracted areas making it 'diiilcult to introduce the dispensing nozzle of a gasoline dispenser into the spout for the filling or supplying of the tank with gasoline. from said dispenser, and inexpensive to manufacture and install.

vWith these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure l is a fragmentary elevation of a gasoline tank constituting an equipment of a motor vehicle and partly in section showing the nozzle constructed inv accordance with the invention, being partly in section, inserted within the iilling spout of said tank for the servicing thereof with gasoline. .f

Figure 2 is a fragmentary enlarged side elevation partly in section of the' said nozzle.

Figure 3 is an end elevation of the nozzle looking toward the discharge end thereof showing in detail the closure associated with said nozzle for the lling spout of the'tank.

Similary reference characters indicate corre-- spending parts throughout the several views in the drawing. 7 Referring to the drawing in detail, A designates generally a portion of a gasoline tank constituting a part of the equipment of a motor vehicle and includes a drum body It, which at its top has in association therewith a filling spout il through which is introduced gasoline into the tank A in the usual Well-known manner, while B denotes generally a gasoline dispensing nozzle being connected witha delivery hose I2 in the usual way and this hose is a part of a gasoline dispenser of those employed at gasolinelling stations.

The nozzle B comprises a valved body I3, the

lvalve mechanism being indicated at It and is of the plunger voperated cut-oil" type. This body I3 is provided with a discharge mouth piece or member I5, itspassage I6 being in communication through the head I3 with the hose I2 for the discharge of gasoline when the piece or member i5 is inserted Within the filling spout II of the tank A, the valve mechanismv being for controlling the delivery of the gasoline into the tank for the lling thereof. i

Swingably connected with the nozzle B at the under side of the body I3 is a trigger I1 which acts directly upon the plunger of the valve mechanism I4 so that the said valve mechanism. can be operated manually in the usual manner for controlling the discharge of gasoline through the nozzle. This trigger is pivoted at i8 to a bearing i9 on the nozzleB and is inconvenient reach to the user of the nozzle B when grasping the latter for the placement of the nozzle in the lling spout II of the tank A so that .the latter can be lled or supplied with gasoline as is commonly done at filling stations.

The part or member I5 of the nozzle B has integrally formed therewith or separably connected thereto an air escape tube 20, which has the portion 2| carried beneath or in juxtaposition to a trigger guard 22 formed on the nozzle B. This portion 2| at its. outer end has fitted therein an air-operated whistle or signal device 23. The end of the tube 20 approaching the free end of the part or member I5 of the nozzle B is removed therefrom and this end is designated at 24 so that when the nozzle is in use for the filling of a gasoline tank A, being engaged in the iilling spout II thereof, there is no chance of gasoline escaping outwardly and discharging from the tube 20 during the lling operation or syphoning action being set up within the tube 20. The air under pressure resultant from the filling of the tank A with gasoline is let oi from within said tank through the tube 2li and during escapement of this air under slight pressure the whistle 23 or other sounding device will operate, signaling an attendant using the nozzle B for the filling of the tank withv gasoline of the fact that such tank is being filled. The instant the gasoline rises within the tank A to a level lling the same, the air through the tube 2U is cut off and the whistle or other like device 23 is silenced thereby giving notice to the attendant that the tank is filled so that the valve mechanism Il may be operated .for the shutting ofi' of the flow of gasoline through 'the nozzle B and in this way gasoline saving is had.

The end 25 carrying the whistle or other device 23 constitutes a seat for a closure, gasket, stopper or the like 26 counterseated within a capping terminal v21 on' the trigger I1 and when the valve mechanism 'I4 is in normal position shutting off gasoline ow through the nozzle B the end 25 of the portion 2| of the tube 20 is closed or sealed. When the valve mechanism Il is operated by the trigger I1 for the flow of gasoline through the `nozzle B, this cap terminal 21 is lifted from the .end 25 and the gasket, stopper or the like 26 removed from the seat constituted by said end 25 and opening the tube 20 so that escape of air under slight pressure will actuate the whistle or signal device 23 when such air passes from within the tank A into the tube 2li concurrently Iwith the lling of the tank A with gasoline. The

Ywhistle or other signaling device 23 constantly sounds or operates during the lling of the tank A with gasoline and the instant that thetank becomes lled with the gasoline the whistle o r other signal device is silenced thereby notifying the attendant using the nozzle B that such tank openings or the filling spouts of varying arranged gasoline tanks A equipped on motor vehicles where the said filling openings or spouts are in restricted or contracted locations thereon. This part 28, when the nozzle B is inserted in the lling opening or spout of the tank A, will make-contact with the mouth 29 and thus seal the same against escapement of gasoline or air from within the tank. The air is adapted to ow outwardly from the tank A through the tube 20 during the use of the nozzle B for the filling of the tank with gasoline. This ow of air operates the whistle or other signal device 23 during the filling operation. Instantly, when the tank becomes lled with gasoline dispensed through the nozzle B, the whistle or other signal device 23 is silenced and in this way notification is had that the tank is filled and the user of the nozzle B cuts oi the flow of gasoline therethrough resulting in the saving of gasoline and avoiding the overlling of the said tank A through Vthe use of said nozzle.

What is claimed is:

1. The combination of a dispensing nozzle having a plunger with a flow control valve therein,

an air escapement tube exteriorly of'said nozzle "for alignment wth the control valve and spaced 2. The combination of a dispensing nozzle having a plunger with a flow ,control valve therein, an air escapement tube exteriorly of said nozzle for alignment with the control valve and spaced therefrom, a signaling device' within said tube and operated by air ilow therethrough, a movable lever forming a trigger arranged within the space between the control valve and the said tube for operating the said control valve and the opening and closing of 'said tube simultaneously, and a pivot connection between the nozzle and sai lever. 3. 'I'he combination of a dispensing nozzle having a plunger with a flow control valve therein, an air escapement tube exteriorly of said nozzle for alignment with the control valve and spaced therefrom, a signaling device within said tube and operated by air flow therethrough., a movable lever forming a trigger arranged within the space between the control valve and the said tube for operating the said control valve and the opening and closing of said tube simultaneously, a pivot connection between the nozzle and said lever, and a head formed on said lever for accommodating an end adjacent thereto of the tube and having a sealing element counterseated therein for contact with the end of said tube.
